Difference Between Physical and Chemical Change
On the basis of whether new substances are formed or not we can classify all the changes into two groups.
Physical change
A change in which no new substances are formed but physical form of the substance changes is known as physical change.
The product formed in such changes is chemically identical to the starting substance.
Chemical change
A change in which one or more substances change into new substances is known as chemical change.
Such a change cannot be reversed easily. Chemical changes are also known as chemical reactions.
